Macro for Visual Studio switching between CPP and header files (Alt + O)
(See link: http://www.codeproject.com/KB/macros/SourceHeaderJumper.aspx) Introduction
How many times C/C ++ programmer swaps between source and header files? Hundreds times per a day! Simple Macros in DTE essentially accelerates swapping action.Create new module, or use existing one, in my case "commonmacros". To convenience, It is necessary link up this macros to hot key, see
Frameworks/base/libmediaplayerservice/mediaplayerservice. cpp
Because MX51 is the working platform, MX51 10.3 code is analyzed. This article mainly analyzes the code of the video play part and ignores the recorder and audio parts.
Mediaplayer service is a system service that allows Android video playback, recording and recording, metadata retrieval, and other client applications to interact with mediaplayer service. mediaplayer service enables video p

I recently wrote a lot of C ++ programs. switching between header files and source files is really painful. There is a macro in vc6.0 to implement this switch, but I found this macro is not useful in vs2008. Like other excellent programmers, I decided to write a macro to implement this function.
If you have not written this macro before, follow these steps:1. Select Tools | Macros IDE in vs and open the macro w

Typedef void foot (); // foot is a function type
Int _ tmain (INT argc, _ tchar * argv []){Foo (); // call directly
STD: cout STD: cout
Foot * pF = Foo; // implicit TransformationPF (); // indirect call via poi
This is a small tool that I usually use to develop C ++ on Unix/Linux. The wrapper, author, and date of the header file can be automatically generated. The CPP file framework can be automatically generated based on the header file. You can automatically generate makefile and unit test.

First, let's take a look at the two functions in our JAVA file. Both functions are very simple. Note that they are static.
package mm.nn.oo; public class CJava { public static String GetStr() { return "THIS STRING IS FROM JAVA!!!"; } public static int Add(int m, int n) { return m + n; } }
Then generate the corresponding. put the CLASS file in the directory mm \ nn \ n \ oo corresponding to the package name, and wait for it to be called by
In python, if the Unix timestamp of the current time is required, I particularly like this:
import timetimestr = time.time()timestamp = int(timestr.split('.')[0])
Here, I like the split function very much. It is available in Java, C #, and python. It is very convenient and you don't have to worry about stepping on mines, but in C/CPP, it will be gone, this is a pity.
